Astigmatism is a common refractive error that affects the shape of the cornea or lens in the eye. This results in blurry or distorted vision, both at a distance and up close. While glasses and contact lenses are effective solutions for correcting astigmatism, some people prefer a more permanent solution. In such cases, eye surgery is often the best option. But with multiple surgical options available, which one is best for correcting astigmatism? In this blog post, we’ll discuss the most common types of eye surgeries for astigmatism and help you determine which one might be right for you.
Understanding Astigmatism and Its Impact on Vision
Astigmatism occurs when the cornea or lens of the eye is shaped irregularly, causing light to be focused on multiple points of the retina, instead of just one. This leads to blurred vision. It can occur along with other refractive errors like nearsightedness (myopia) or farsightedness (hyperopia). The symptoms of astigmatism include:
Blurry or distorted vision
Eye strain or discomfort
Headaches
Difficulty seeing clearly at night
Astigmatism can affect both children and adults, and in most cases, it is easily diagnosed through a routine eye exam.
1. LASIK (Laser-Assisted in Situ Keratomileusis) Surgery: The Most Popular Option
One of the most popular surgical treatments for astigmatism is LASIK (Laser-Assisted in Situ Keratomileusis) surgery. This procedure uses a laser to reshape the cornea, improving the way light enters the eye and focusing it more accurately on the retina. LASIK is known for its precision, fast recovery time, and high success rates.
A. How LASIK Works
During LASIK surgery, the eye surgeon uses a laser to create a thin flap in the cornea. Once the flap is created, the surgeon uses another laser to reshape the cornea, correcting the irregular curvature that causes astigmatism. After reshaping, the flap is carefully repositioned, where it naturally adheres without the need for stitches.
B. Benefits of LASIK for Astigmatism
Quick recovery: Most patients notice improved vision within 24 to 48 hours.
Minimal discomfort: The procedure is virtually painless, and recovery is usually fast.
Long-lasting results: LASIK provides a permanent solution for astigmatism correction.
High success rate: LASIK has a proven track record for correcting astigmatism effectively.
C. Considerations
While LASIK is a great option for many, it may not be suitable for individuals with very thin corneas or severe astigmatism. A thorough eye examination is necessary to determine if LASIK is the best choice for you.

2. PRK (Photorefractive Keratectomy): A Good Alternative to LASIK
PRK is another laser eye surgery option for correcting astigmatism. Like LASIK, PRK also uses a laser to reshape the cornea, but the process differs in how the cornea is treated.
A. How PRK Works
In PRK, the surgeon removes the thin outer layer of the cornea (the epithelium) before using the laser to reshape the corneal tissue underneath. Unlike LASIK, PRK does not require the creation of a flap. After the laser treatment, the epithelium regenerates naturally over time.
B. Benefits of PRK for Astigmatism
No risk of flap complications: Since there is no flap created in PRK, the risk of flap-related complications is eliminated.
Suitable for thin corneas: PRK is an excellent option for patients who may not qualify for LASIK due to thin corneas.
Permanent results: Like LASIK, PRK offers a long-lasting solution for astigmatism.
C. Considerations
The recovery time for PRK is longer than LASIK. It may take several days to weeks for vision to fully stabilize. However, PRK is still a highly effective procedure for correcting astigmatism.
3. SMILE (Small Incision Lenticule Extraction): A Newer, Minimally Invasive Option
SMILE is a newer, minimally invasive laser eye surgery technique for treating astigmatism. It stands out as an option that requires only a small incision, making it less invasive than LASIK.
A. How SMILE Works
During SMILE surgery, the surgeon uses a femtosecond laser to create a small lens-shaped piece of tissue (lenticule) within the cornea. This lenticule is then removed through a small incision, which reshapes the cornea and corrects the refractive error, including astigmatism.
B. Benefits of SMILE for Astigmatism
Less invasive: With only a small incision, SMILE is less invasive than LASIK and does not require a corneal flap.
Quick recovery: SMILE typically offers a quicker recovery compared to LASIK or PRK.
Suitable for high prescriptions: SMILE can treat higher degrees of astigmatism effectively.
C. Considerations
SMILE is a relatively new procedure and may not be as widely available as LASIK or PRK. It is also generally considered a more advanced procedure, requiring highly skilled surgeons.
4. Astigmatic Keratotomy (AK): A Surgical Procedure for Severe Astigmatism
Astigmatic keratotomy (AK) is a surgical option for people with more severe forms of astigmatism. This procedure involves making small, precise incisions on the steepest part of the cornea to flatten it, improving the way light enters the eye.
A. How AK Works
During AK, the surgeon uses a small surgical blade to make incisions in the cornea. These incisions flatten the steep part of the cornea, reducing astigmatism. AK is often combined with other procedures, such as cataract surgery, for individuals with both cataracts and astigmatism.
B. Benefits of AK for Astigmatism
Effective for severe astigmatism: AK is often used to correct higher degrees of astigmatism that cannot be treated with LASIK or PRK.
Can be combined with cataract surgery: AK is frequently used in combination with cataract surgery to address both issues simultaneously.
C. Considerations
AK requires a longer recovery period compared to LASIK and PRK. It may also not be as precise as laser-based procedures, depending on the surgeon’s experience and technique.
5. Toric Intraocular Lenses (IOLs): A Solution for Astigmatism with Cataracts
For patients with both cataracts and astigmatism, toric intraocular lenses (IOLs) can provide a solution. These lenses are designed to correct astigmatism during cataract surgery.
A. How Toric IOLs Work
Toric IOLs are specially designed lenses that are implanted during cataract surgery to correct the refractive error caused by astigmatism. They help to focus light properly on the retina, reducing or eliminating the need for glasses or contact lenses after surgery.
B. Benefits of Toric IOLs
Dual treatment: Toric IOLs treat both cataracts and astigmatism at the same time.
Long-lasting results: Once implanted, toric IOLs provide permanent vision correction.
C. Considerations
While toric IOLs are highly effective, they may not be suitable for patients with severe astigmatism or other eye conditions.
Choosing the Best Surgery for Astigmatism
When choosing the best surgery for astigmatism, several factors must be considered, including:
Severity of astigmatism: Mild to moderate astigmatism may be best treated with LASIK or PRK, while more severe cases may require AK or toric IOLs.
Eye health: Conditions such as dry eye, thin corneas, or other eye health concerns may influence which surgery is best for you.
Recovery time: LASIK and SMILE offer quicker recovery times, while PRK and AK may require longer healing periods.
Lifestyle and expectations: Your surgeon will discuss your vision needs and lifestyle to help determine the most suitable procedure for your case.
If you are considering best LASIK eye surgery in Gurgaon, consult with an experienced eye surgeon who can provide personalized advice and treatment options tailored to your specific needs. With advanced technology and expert care, LASIK surgery in Gurgaon can offer a permanent solution to astigmatism and help you achieve clear, healthy vision.
